Discusses natural language retrieval systems, focusing on West Publishing Company's WIN (Westlaw Is Natural) system used with its case law database. Information retrieval models, the advantages and disadvantages of natural language retrieval, and the use of the approach by Congressional Quarterly's Washington Alert, Personal Librarian, and other…

Presents specifications for software that is designed to support manual development and maintenance of information retrieval thesauri. Evaluation of existing software and design of custom software is discussed, requirements for integration with larger systems and for the user interface are described, and relationships among terms are discussed.…

Describes how online searchers can use a software tool based on back-of-the-book indexes to assist in dealing with search engine databases compiled by spiders that crawl across the entire Internet or through large Web sites. Discusses human versus machine knowledge, conversion of indexes to mind maps or mini-thesauri, middleware, eXtensible Markup…

Reviews several mechanisms to support navigation in hypertext following a brief discussion of the phenomena of disorientation in hyperspace. Categorizes ways to support navigation in terms of the following: solutions regarding the tools to support navigation; solutions regarding interface and navigation metaphors; and solutions regarding hardware…

Examines several alternative document summarization techniques to determine which is the most effective for saving time when a human judge must certify the output of an automatic categorization system. That is, how useful is the summarization technique as compared to reading the entire document. Users in this case are molecular biologists wanting…

Different people have a diversity of needs and expectations when approaching an information retrieval system, and providing people with the ease and efficiency to access information is important when designing systems. By examining the man-machine interface from the cognitive viewpoint, it is possible to investigate how a person interacts with an…

NETPAD is a microcomputer-based system, implemented on a Commodore PET 2001-8, by which a human indexer can input, retrieve, and edit information in order to produce a variety of permuted index displays. The basic unit of the NETPAD system is a subnetwork (a description of a single document) containing a set of concept nodes (author, title, date,…

This study was designed to be a state-of-the-art survey and investigation of intelligent "front end" design approaches and software for improving subject access and subject searching in today's large online bibliographic retrieval systems and online public access catalogs (OPACS). The report begins with an illustrated overview of…

Using as a backdrop Vannevar Bush's 1945 discussion of the "Memex," his proposed system for organizing and storing information, this paper considers the development of intelligent multimedia knowledge systems. Particular attention is focused on learner needs and intentions in information seeking, and the implications of these factors for…

The realization that the facilities available for the retrieval of scientific and technical information were being underutilized resulted in a project undertaken by the Drexel University School of Library and Information Science to develop a computer intermediary capable of assisting users of scientific and technical information in the performance…

This bibliography lists 162 unclassified - unlimited reports acquired by DDC, with their abstracts, grouped into five general subject areas: programing (computers), information retrieval, time sharing, graphics, and general applications. The topical arrangement is complemented by four indexes: corporate author/monitoring agency, personal author,…

Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in…

The unclassified and unlimited bibliography compiles references dealing specifically with the role of computers in information sciences. The volume contains 249 annotated references grouped under two major headings: Time Shared, On-Line, and Real Time Systems, and Computer Components. The references are arranged in accesion number (AD-number)…

This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half…

Discusses the CODER system, which was developed to investigate the application of artificial intelligence methods to increase the effectiveness of information retrieval systems, particularly those involving heterogeneous documents. Highlights include the use of PROLOG programing, blackboard-based designs, knowledge engineering, lexicological…
